The transfer rate of our Secure Digital varies depending on its classification. Our Signature line SD (40X) has a read speed of 6MB/s and write speed of 5MB/S. Our Extreme Performance line (60X) has a read speed of 9MB/s and write speed of 8MB/s. Finally our Extreme Performance Plus (133X) has a read speed of 20MB/s and write speed of 16MB/s. Our miniSD has a read speed of 8MB/s and write speed of 3MB/s.

Please see attachment for compatibility list. For any devices not on the list, we would recommend contacting the device manufacturer to see if a particular device is supported or if a future firmware upgrade will allow the device to work.

Unfortunately we do not have any methods of data-retrieval. If data needs to be extracted from a drive we would would recommend sending it in to a data retrieval lab as they would have the specialized tools to do so.

SDXC is the newest SD memory card specification that supports memory capacities above 32GB up to 2TB. Host devices that are compliant to the SD Physical Layer and File System 3.00 version specs can support SDXC memory cards as well as SDHC and standard SD cards.

Because SDXC uses a different file system called 'exFAT' and works differently then standard SD cards, this new format is NOT backwards compatible with host devices that only take SD (16MB to 2GB) or SDHC (4GB to 32GB) cards. To ensure compatibility, look for the SDXC logo on cards and host devices (cameras,
camcorders, etc).

UHS-I Stands for 'Ultra High Speed-Interface.' Cards with UHS-I marking are capable of supporting data transfer speeds up to 104 Megabytes per second. The new high-speed symbols are designed to make it easier for consumers to
take advantage of the massive storage and incredible speeds offered in SDXC and SDHC products.
